slow moving melee units that multiply after eating enemy corpses
Book of Dagon
As the city grew so did it's disease and rott. All the fish that was wasted in heaps on the shores of Karlshaven were filled with maggots, all the cows and pigs in the farms that were slaughtered in sacrifice would crawl with maggots. All the people that lived in the city fearing the day their name would send them into the pit were all filled with maggots. This life is a feast for the dead.
